GENERAL DESCRIPTION
The MX26C4000C is a 5V only, 4M-bit, MTP EPROMTM
(MultipleTime Programmable Read Only Memory).It is
organized as 512K words by 8 bits per word, operates
from a single + 5 volt supply, has a static standby
mode, and features fast single address location program-
ming. All programming signals areTTL levels, requiring
a single pulse. It is design to be programmed and erased
by an EPROM programmer or on-board. The
MX26C4000C supports a intelligent fast programming
algorithm which can result in programming time of less
than one minute.
This MTP EPROMTM is packaged in industry standard
32 pin dual-in-line packages, 32 lead PLCC, 32 lead SOP
and 32 leadTSOP packages.

to the Read Mode. Robust design features prevent inad-
vertent write cycles resulting from VCC power-up and
power-down transitions or system noise.To avoid initia-
tion of write cycle during VCC power-up, a write cycle is
locked out forVCC less than 4V.The two- command pro-
gram and erase write sequence to the command regis-
ter provide additional software protection against spuri-
ous data changes.
FUNCTIONAL DESCRIPTION
When the MX26C4000C is delivered, or it is erased, the
chip has all 4M bits in the "ONE", or HIGH state.
"ZEROs" are loaded into the MX26C4000C through the
procedure of programming.
ERASE ALGORITHM
PROGRAM VERIFY MODE
The MX26C4000C do not required preprogramming be-
fore an erase operation.The erase algorithm is a close
loop flow to simultaneously erase all bits in the entire
array.Erase operation starts with the initial erase opera-
tion. Erase verification begins at address 0000H by read-
ing data FFH from each byte. If any byte fails to erase,
the entire chip is re-erased to a maximum for 10 pulse
counts of 500ms duration for each pulse.The maximum
cumulative erase time is 5s.However, the device is usu-
ally erased in no more than 3 pulses. Erase verification
time can be reduced by storing the address of the last
byte that failed. Following the next erase operation veri-
fication may start at the stored address location.JEDEC
standard erase algorithm can also be used. But erase
time will increase by performing the unnecessary pre-
programming.
Verification should be performed on the programmed bits
to determine that they were correctly programmed.
Verification should be performed with OE and CE, at
VIL, and VPP at its programming voltage.
ERASE VERIFY MODE
Verification should be performed on the erased chip to
determine that the whole chip (all bits) was correctly
erased. Verification should be performed with OE and
CE at VIL, and VCC = 5V, VPP = 12.5V
AUTO IDENTIFY MODE
PROGRAM ALGORITHM
The auto identify mode allows the reading out of a bi-
nary code from MTP EPROM that will identify its manu-
facturer and device type. This mode is intended for use
by programming equipment for the purpose of automati-
cally matching the device to be programmed with its
corresponding programming algorithm. This mode is
functional in the 25°C ±5°C ambient temperature range
that is required when programming the MX26C4000C.
The device is programmed byte by byte.The maximum
program puls is 25 pulses, each of 50us duration is al-
lowed for each byte being programmed. The byte may
be programmed sequentially or by random. After each
program pulse, a program verify is done to determine if
the byte has been successfully programmed.
To activate this mode, the programming equipment must
force 12.0 ±0.5 V on address line A9 of the device. Two
identifier bytes may then be sequenced from the device
outputs by toggling address line A0 from VIL to VIH. All
other address lines must be held atVIL during auto iden-
tify mode.
Programming then proceeds to the next desired byte
location. JEDEC standard program algorithms can be
used.
DATA WRITE PROTECTION
Byte 0 ( A0 = VIL) represents the manufacturer code,
and byte 1 (A0 = VIH), the device identifier code. For
the MX26C4000C, these two identifier bytes are given
in the Mode Select Table. All identifiers for manufac-
turer and device codes will possess odd parity, with the
MSB (DQ7) defined as the parity bit.
The design of the device protects against accidental era-
sure or programming.The internal state machine is auto-
matically reset to the read mode on power-up. Using
control register architecture, alteration of memory can
only occur after completion of proper command se-
quences.The command register is only active whenV PP
is at high voltage. whenV PP = V PPL , the device defaults

MX26C4000C
READ MODE
The MX26C4000C has two control functions, both of
which must be logically satisfied in order to obtain data
at the outputs. Chip Enable (CE) is the power control
and should be used for device selection. Output Enable
(OE) is the output control and should be used to gate
data to the output pins, independent of device selection.
Assuming that addresses are stable, address access
time (tACC) is equal to the delay from CE to output (tCE).
Data is available at the outputs tOE after the falling edge
of OE, assuming that CE has been LOW and addresses
have been stable for at least tACC - tOE.
STANDBY MODE
The MX26C4000C has a CMOS standby mode which
reduces the maximum VCC current to 100 uA. It is
placed in CMOS standby when CE is at VCC ± 0.3 V.
The MX26C4000C also has aTTL-standby mode which
reduces the maximumVCC current to 1.5 mA. It is placed
in TTL-standby when CE is at VIH. When in standby
mode, the outputs are in a high-impedance state, inde-
pendent of the OE input.
SYSTEM CONSIDERATIONS
During the switch between active and standby condi-
tions, transient current peaks are produced on the rising
and falling edges of Chip Enable. The magnitude of these
transient current peaks is dependent on the output ca-
pacitance loading of the device. At a minimum, a 0.1 uF
ceramic capacitor (high frequency, low inherent induc-
tance) should be used on each device between VCC
and GND to minimize transient effects. In addition, to
overcome the voltage drop caused by the inductive ef-
fects of the printed circuit board traces on EPROM ar-
rays, a 4.7 uF bulk electrolytic capacitor should be used
between VCC and GND for each of the eight devices.
The location of the capacitor should be close to where
the power supply is connected to the array.
OUTPUT DISABLE
Output is disabled when OE is high.When in output dis-
abled all circuitry is enabled. Except the output pins are
in a high impedance state (Hi-Z).
